[WriteLog] MMTTY Plugin FSK Troubles

[The Trench Family]

I'm really stuck and frustrated.  I want to run FSK keying.  The symptoms
are that I am unable to get any FSK keying out of COM4 using the MMTTY
Plugin.

I have been successful at getting things to play using the native MMTTY
program, but unsuccessful at getting it to work with the MMTTY plug-in to
Writelog.  

I have also been successful at getting things to work when I set the TU TYPE
to Dumb Terminal.

I strongly suspect some type of software setup problem with Writelog,
Rttyrite or the MMTTY plugin, but I can't isolate it.  (Configuration info
is provided below.)

A few other oddities:

I use the LPT for CW and PTT.  (I have use Direct I/O.)  I have disabled
Direct I/O, but something is still operating the PTT function.

I have been successful at getting the MMTTY plug-in to play through COM1.

Any thoughts or advice?
